PATENT OFFICE.,

LOOSE-LEAF BINDER.

SPECIFICATION forming part of Letters Patent No. 763,583, dated June 28,1904.

Application led January 16, 1904. Serial No. 189,322. (No model.)

T0 MZ whom t may concern:

Be it known that I, GAvIN PERRY WILLIAMS, a citizen of the UnitedStates, and a resident of Milwaukee, in the county of Milwaukeek andState of Wisconsin, have invented certain new and useful Improvements inLoose- Leaf Binders; and I do hereby declare that the following is afull, clear, and exact description thereof.

Myinvention relates to that class of blankbook binders in which theleaves are separate and removable; and it consists in certain novelfeatures of construction and combination of parts inthe devices forholding said leaves in place and for the ready removal, insertion, orsubstitution of such leaves, all as will be fully set forth hereinafter,inconnection with the accompanying drawings, and subsequently claimed.

In the said drawings, Figures 1 and 2 are transverse sectional viewsthrough a book embodying my said invention, taken, respectively, on theplanes indicated by the lines 1 1 and 2 2 of Fig. 3; and Fig. 3 is aplan view of said book open and with the fastening devices also open forthe reception of the said loose leaves.

Referring by numerals to the said drawings, 1 2 indicate the covers of abook to which my devices are attached, and 3 the back of said book.

4 designates a strip of any suitable fabric or iieXible sheet (such asrubber or rubber cloth) to which my devices are secured in any suitableway, as hereinafter described, the side edges of said strip or sheetbeing then secured (as by cementing, riveting, or otherwise) to theinner surface of the said covers 1 2.

5 indicates a channeled supporting-plate, preferably of thin sheetmetal, herein shown as having its side edges bent under toward eachother around the edges of a pasteboard or other strip 6, which strip isbeneath the fabric sheet 4, which latter is interposed at the edgesbetween said strip@ and the plate 5, all being secured together, as bestshown in Figs. 1 and 2, by crimping the edges of the said plate 5, sothat said plate occupies the space at the back of the book when thelatter is closed. The said plate has a longitudinal polygonal-facedchannel for the receptionv of a correspondingly polygonal-shaped rod 7,from one face of which there rise ring-sections 8, having preferablypointed ends 9, which engage when the rod is properly turned with otherring-sections 10, having, preferably, end sockets 11 to receive the saidpointed ends 9 and complete the said rings, these sections 1() risingfrom the plate 5. The rod 7 is preferably formed with a milled head l2rigid therewith for convenience in manipulation, and the rod is held inplace by springs 13, secured adjacent to one edge of the plate 5 andextending transversely over said rod .nea-r said rings, the free ends ofthese springs being bent to conform to the shape of two adjacentpolygonal faces of the said rod.

. The operation of my device will be readily understood from theforegoingdescription of its construction, taken in connection with theaccompanying drawings. In the position of the parts shown in full linesthe rings are open, and any desired number of loose leaves (eachperforated at the edge in line with said rings) can be slipped on thering-sections 10 10, after which a slight turn of the rod 7 will bringthe sections 8 8 into engagement with said sections 10 10, as indicatedby dotted lines in Fig. 1, therod? being readily turned by its head 12under the springs 13 13, which yield sufficiently to enable this to bedone, and then instantly snap down again, securely holding the rod inits new position, and thereby securing the loose leaves in position uponthe rings. To enable a leaf or leaves to be removed, the rod 7 can bequickly turned in the reverse direction, thereby opening the ringsagain, as shown in the drawings.

Having thus describedmy invention, what Iclaim as new, and desire tosecure by Letters Patent, is-

In a binder for loose leaves, the combination with a plate having alongitudinal channel formed therein having two plane sides at an angleto each other,of a rotatable polygonalfaced rod located therein,spring-detente; sehave hereunto set my hand, at Milwaukee, in cured tosaid plate and extending transversely the county of Milwaukee and Stateof Wisover said rod, and shaped at their free ends consin, in thepresence of two witnessses. to conform to two adjacent faces of saidrod, v G. P. WILLIAMS. 5 and opposed ring-sections, rising from saidWitnesses:

plate and said rod respectively. H. G. UNDERwooD, In testimony that Iclaim the foregoing I GEO. WV. YOUNG.
